It sure does. I'll continue my calibrating with renewed enthousiasm. I,m positive that, my braincell will be able to get to grips with it. I'll will inform you of inevitable success. Geary, my postings shouldn't daunt you in anyway. I'm convinced your braincells, being a collective, will have no trouble at all. Dr. Phill, Dr. Ross, thanks for your generous help. This is indeed a great forum. All knowledgeable people seem to be here. If one of you told me that Dr Rudman is also a member, I would be flabbergasted.

Thanks again
